Everywhere I look I find WPF/Silverlight developers who believe a very popular myth: You cannot update a ViewModel or an ObservableCollection from a non-UI thread. Like most myths, there is an element of truth here. But not understanding that truth can lead you to some very elaborate solutions. Here’s...

There are several major architectural approaches used in building user interfaces. MVC, MVP and MVVM seam to be the most popular of the bunch. From among them, MVVM has risen to the top of the stack for WPF and Silverlight developers. Even ignoring the question “Why use separated presentation at...

As a follow-up to my last post on MVVM , I want to further investigate the ViewModel as a concept. In commenting on my blog, one reader describes a ViewModel as “a UI oriented abstraction of the model.” In that sense, he is saying that a ViewModel (VM) is simply a contextual “View of...

There’s been a lot of talk lately about MVVM (Model-View-ViewModel) in the WPF and Silverlight space.

Today is a long awaited day for me. Caliburn is now in official Beta. There have been many bug fixes and a ton of new features since the Alpha release last October. We’ve also been dogfooding it on several projects, one of which is NHProf . I wanted to use this post as an opportunity...

Caliburn has a new home on CodePlex . You can find it at http://www.codeplex.com/caliburn . Additionally, I have added a full set of documentation that is available online . The documentation loosely follows the samples I have created for the framework which can be found in the 'samples'...

Details here . As far as I can tell from the docs, they removed a lot of things, made a bunch of things private or internal and changed the signatures of some things here and there.
